Pressure Relief Valve DBW 30 BG2-5X/315U6EG12N9K4/12 - Bosch Rexroth R978911931

Where the on-board system runs 12 V, the valve solenoid has to be rated for it. The pilot-operated pressure relief valve DBW 30 BG2-5X/315U6EG12N9K4/12 works at 12 VDC, covers 2 to 315 bar and relieves up to 650 l/min through the threaded connection.

Benefits

• Supply voltage 12 VDC, the solenoid is wound for that level.
• Setting range 2 to 315 bar, symbol B, two ports.
• Threaded connection, fitted into existing size 32 piping.
• Unloading through a built-on directional spool valve, poppet seat design.
• 5.05 kg, NBR seals, up to 650 l/min, HL hydraulic fluid.

Application

Mobile power units, attachments and test trolleys feed their valves from a 12 V supply. A matching coil voltage saves a separate converter in the cabinet. The built-on solenoid switches the circuit pressureless as soon as the drive rests.
